The Foam N’ Seal™ FNS800 30″ Long Barrel Foam Sealant and Adhesive Dispensing Gun is great for applications that are difficult to reach. It is commonly used for weatherization air sealing, subfloor installation, structural insulation panel (SIP) installation, and for pest control in filling cracks and holes. The 30″ long gun features a lightweight reinforced aluminum body and a comfortable handle for a perfect grip. It dispenses consistent foam on every job, and allows precise control of foam dispensing form to fill small gaps, cracks and and large voids and for applying flooring adhesives. The stainless steel foam can adaptor is Teflon coated for greater non-stick and reliable performance. This gun is reusable up to 30 days.

The FNS800 is a cheaper alternative to the Dow Great Stuff Pro 14 Long Barrel 26.5″ foam insulation gun, Touch ‘n Seal Sharpshooter Long Barrel gun foam applicator, Todol Pageris GU24, and the Tytan Pro Long Barrel foam gun. It may be cheaper than the Dow Great Stuff Pro 14 Long Barrel foam gun, but the FNS800 is a better value as it offers similar features and performance. We also offer a 45″ long barrel version of the FNS800. The FNS850 is identical to the FNS8oo but has a longer barrel.
